Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

When you strip away all the misleading and inaccurate rhetoric, here’s the one set of numbers that really matters. If we believe the President’s forecasts (which may be a best-case scenario), the burden of federal spending will grow by $2 trillion between this year and 2022.

In all likelihood, the actual numbers will be worse than this forecast.

The President’s budget, for instance, projects that the burden of federal spending will expand by less than 1 percent next year. That sounds like good news since it would satisfy Mitchell’s Golden Rule.

But don’t believe it. If we look at the budget Obama proposed last year, federal spending was supposed to fall this year. Yet the Obama Administration now projects that outlays in 2012 will be more than 5 percent higher than they were in 2011.

The most honest assessment of the budget came from the President’s Chief of Staff, who openly stated that, “the time for austerity is not today.”

With $2 trillion of additional spending (and probably more), that’s the understatement of the century.

I’ve already pointed out that the budget could be balanced in about 10 years if the Congress and the President displayed a modest bit of fiscal discipline and allowed spending to grow by no more than 2 percent annually.

But the goal shouldn’t be to balance the budget. We want faster growth, more freedom, and constitutional government. All of these goals (as well as balancing the budget) are made possible by reducing the burden of federal spending.
